Parameters:
ctx CAMELLIA context
mode CAMELLIA_ENCRYPT or CAMELLIA_DECRYPT
length length of the input data
iv initialization vector (updated after use)
input buffer holding the input data
output buffer holding the output data

void camellia_crypt_cfb128 ( camellia_context ctx,

)

CAMELLIA-CFB128 buffer encryption/decryption.

Parameters:
ctx CAMELLIA context
mode CAMELLIA_ENCRYPT or CAMELLIA_DECRYPT
length length of the input data
iv_off offset in IV (updated after use)
iv initialization vector (updated after use)
input buffer holding the input data
output buffer holding the output data

void camellia_crypt_ecb ( camellia_context ctx,
int  mode,
unsigned char  input[16],
unsigned char  output[16] 
)

CAMELLIA-ECB block encryption/decryption.

Parameters:
